cGas Ammonia Vent Line Transmitter - Addendum Rev. B | 2022.09
12 © 2022 All rights reserved. Data subject to change without notice.
NOTE: A calibration label should be applied after every calibration to conrm work performed
and the date it was conrmed. If a controller is involved, the alarm set points should be
indicated on a label on the front door of the enclosure so anyone working in the environment
can be aware.
5.1 Remove Detector from Vent Stack
The cGas Ammonia Vent Line Detector must be removed from the vent stack in order to
calibrate the sensor.
On the back of the device, a long pipe tting is connected with a coupler to the mounting pipe
on the vent stack to secure the device in place. Unscrew the wide ring portion of the coupler
and carefully remove the device from the mounting pipe. Be careful to not handle the device
roughly resulting in disconnecting or loosening the wires.
IMPORTANT: The catalytic sensor is very susceptible to shock - when working with the
sensor do not hit it. Manually loosen then senso. When replacing the tting does not have
to be pressurized, so minimal tightness is all that is required.

WARNING: When you remove the device, the vent stack will be exposed and ammonia
may leak into the air. Vent line systems should always be treated with extreme caution and
workers should assume a relief valve could release at any time. Take all necessary safety
precautions and follow industry standard practices and local regulations when calibrating the
cGas Ammonia Vent Line Detector.
